* Implement syscall handlers using a source generator * Copy FlushProcessDataCache implementation to Syscall since it was only implemented on Syscall32 * Fix wrong argument order in some syscalls * Delete old Reflection.Emit based syscall handling code * Improvements to the code generation * ControlCodeMemory address and size is always 64-bit
